Heart rate variability (HRV) is regularly assessed in neuroimaging studies as an indicator of autonomic, emotional or cognitive processes.In this study, we investigated the influence of a loud and cramped environment during magnetic resonance imaging (MRI) on resting HRV measures.We compared recordings during functional MRI sessions with recordings
The modelling is widely used in determining the best strategies for the mitigation of the impact of infectious diseases.Currently, the modelling of a complex system such as the spread of COVID-19 infection is among the topical issues.The aim of this article is graph-based modelling of the COVID-19 infection spread.The article investigates the studi
If the low-frequency and large-scale oscillation of the traction grid voltage continues, the grid voltage protection of locomotive or EMU traction system will be influenced, resulting in Toddler converter traction blocking and affecting the normal operation of the train.In view of this practical engineering problem, the main influencing factors of
